BUTTON HOLE CUTTER. No. 316,366. 1 Patented Apr. 21', 1885.

mam ST TES ATFENT FFICEQ \VILFORD O. HUDSON AND JOHN BARRY, OFOHILLIOOTHE, OHIO, SAID BARRY ASSIGNOR' OF ONE-HALF HIS RIGHT TO JOHN G.ENTREKIN,

OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 316,366, dated April21, 1885.

Application filed August 8, 1884. (Model) Be it known that we, WVILFORDG. HUDSON and JOHN BARRY, both of Ohillicothe, Ross county, Ohio, havejointly invented new and useful Improvements in Button-Hole Gutters, ofwhich the following is a specification.

Our invention relates to improvements in those buttonhole cutters whosecutting parts or members are attached to or constitute portions of twoarticulated jaws working on the principle of a pair of shears.

Our invention comprises a device for holding the goods level on eachside of the cutterblade and for pressing the said blade firmly againstits counter.

Our invention further comprises devices for regulating the length of cutand the uniform distance of the holes from the edge of the goods andfrom each other.

In the accompanying drawings, Figure l is a perspective view of abutton-hole cutter embodying ourinvention, said cutter being shown setto cut a button-hole of medium size, and being represented in the opencondition. Figs. 2 and 3 are respectively right and leftside views ofthe jaws of such cutter, the instrument being shown in its closedcondition, the two viewsrepresentingthe ripper-hook, onein the unfoldedand the other in the folded condition. Fig. 4 is a top view of thelower-jaw.

A represents the lower or counterjaw, and B-the upper jaw, of abutton-hole cutter, the two jaws having the customary articulatingpivot, O, and terminating in the accustomed bows or handles, A B.

Screwed or otherwise firmly fastened to the top of the lower or counterjaw, A, is a steel bit, D, whose portion at nearest the upperjawconstitutes the lower cutting-edge or counter proper. This bit ispreferably let in flush, or nearly so, with the top of said jaw.

In a suitable recess in the upperjaw, B, is screwed a triangular blade,E, of steel. The body of the blade is formed concave, so as to permitonly its inclined cutting-edge to bear on the cutting-edge of the bit.The rear edge or heel of this blade is formed concave and concentricwith the pivot G to prevent the goods slipping away by the outwardpressure of the closing-blades, and so insure a shear-cut of the exactlength desired.

Attached to the right-hand side of the counter-jaw A, and occupyingreentrant angle at of bit D, is a piece of steel that constitutes anauxiliary laterally yielding and pressing support or spring, F. Theupper surface of said spring F is flush with that of the bit D. Saidsprings resilience, causing it to press closely against the back ofblade E as the latter descends in the act of cutting, serves to holdsaid blade firmly against said bit, while said springs upper surfaceoperates to support that part of the goods which is situated on theinside side from the bit D.

To enable adaptation of the instrument to out button-holes of anydesired uniform length, the'extension of the jaw A immediately behindthe pivot O has tapped within 'it a gagescrew, G, whose point 9 abutsagainst the corresponding extension of the jaw 13.

A circular scale, H, at the periphery of the pivot 0 enables theoperator to know when the screw is sufficiently advanced to gage theinstrument to the desired length of out. For still nicer accuracy thescrew-head g may have radial graduations 9.

To enable uniform distancing of the buttonholes from the edge of thegarment,we provide a slidable gage, I, whose slot z receives a setscrew,J, by which said gage may be fixed at any desired distance from the heelc of the cutting-blade.

Any desired uniform distancing of the consecutive button-holes may befacilitated by an adjustable gage consisting of a rod, K, which ismarked off with any desired linear measurements, and which occupies atransverse orifice, a, in the jaw A, and is retained to any specificadjustment by means of a set-screw, 'L. An upwardly-directed spun-k, atsaid gages left end enables accurate application to each lastcutbutton-hole in succession. The other eX- tremity of said gage may takethe form of a small hook, it, suitable for picking out bastingstitches,81c.

There may be pivoted to that side of the .jaw and the blade secured tothe upper jaw,

jaw A which is remote fromthe cutting-blade I D a ripping-knife, M,which, when desired for use, may be unfolded, as in Figs. 1, 2, and 4,and at other times may occupy a recess, a, in said jaw, as in Fig. 3.

An important feature of ourinvention is the auxiliary counter or springF, which, by the prevention of sagging of the goods on the inside, andby the prevention also of any spreading apart of the cutters, insures asharp, accurate, and easy out.

We claim as new and of our invention- 1. The combination,with the loweror counter jaw and a spring secured at oneiend thereto and having itsfree end extending forward, of the the upper jaw and the blade securedthereto, the free end of the spring forming an additional support to thegoods and bearing on'the lower or counter jaw and the blade workingbetween the lower or cou nter jaw and the spring.

2. The co1nbination,withthelower or counter jaw having a re-entrantangle, (1, and a spring secured to the lower or counter jaw and havingits free end occupying the mentrant angle, of the upper jaw and a bladesecured thereto, the blade working between the lower or counter jaw andthe spring.

3. The combination,with the lower or counter jaw and the bit D, havingre-entrant angle (1, and of the yielding spring F, of the upper theyielding spring being flush with the said bit and occupying there-entrant angle d thereof.

4. The combination of the lower or counter jaw, A, having the separablebit D, formed with a cutting-edge, d, and re-entrant angle d,'the jaw B,having separable blade E, formed with concave heel e, pivot G, and thespring F, the concave heel being concentric with the pivot and thespring being securedto thelower or counter jaw'yielding laterally havingits free end occupying the re-entrant angle and its upper surface flushwith the bit.

5. The combination of the jaws A and B, having handles A and B,respectively, pivot 0, having a circular scale, H, on the peripherythereof, and an adjustable gage-screw, ,G, working through one handleand bearing on the other handle, and having a head, 9, provided withgraduations g".

6. The adjustable gage K, having an upwardly-directed spur, k, forinsertion in abutton-hole, in combination with a jaw having a holethrough which the gage is adjusted transversely of the jaw.

7. The combination of the gage K and the thread-picker k.

8. The combination, with the lower or counter jaw, A, having a recess,a, of the folding ripper hook or knife M pivoted in the recess.
